Navigation SMARTY UK WEB PAGES

I am a 75 pensioner at the end of 2020 I had to undergo emergency surgery to relive pressure  on my brain pressure from a  cyst  miss diagnosed sinus infection I have two phones a smart phone and a simple phone my wife also has a smart phone. We have these in case an emergency call needs to be made in case we lose connection on the now ViOP connection we have instead of the standard land line. The ViOP connection can be lost if broadband goes' down  or Electricity Failure. I tried to or three sims on line but this was denied I even tried on a customer service conversation which also denied this possibility but the conversation with the message that it was easy to join SARTY MOBILE. I bought 3 sims from Argos in an attempt to resolve my problem in my attempt to resolve my problem. I told by customer service  "It was easy to join SARTY MOBILE."  Far from it the web are a maze not very  intuitive in try to register my bought sims alongside the PAC numbers I have now been sent 4 sims in the post trying to set up a group of the three phones  seem to be not very intuitive also. Have to go now feeling fatigue now not good for me. Thanks' All.
